Just to add to Torfinn's post. I strongly suspect Torfinn is referring to new drawings, where, because there is noting in the drawing there is nothing to select, hence the select doesn't work. TC has been programmed this way for many years.
With respect to existing drawings where there is something in the drawing, the spacebar or select icon should work, however in later versions (2016 / 2017) I have noticed that sometime I have to press the space two or three times for it to stick, I never bothered trying to find out if it was TC or Windows which was delaying the spacebar command, easier just to press it until it works.
Does it work for you with existing drawings (not templates) ?.
